engineering draft guideline-alv-s1-4 application guidelines guidelines-1 1. circuit design 1.1 operating temperature and frequency electrical parameters for electrolyt ic capacitors are normally specified at 20 temperature and 120 hz frequency. these parameters vary with changes in temperature and freq uency. circuit designers should ta ke these changes into considera tion. (1) effects of operating temperature on electrical parameters a) at higher temperatures, leakage current and capacitance increase while equivalent series resistance (esr) decreases. b) at lower temperatures, leakage current and capacitance decrease while equivalent series resistance (esr) increases. (2) effects of frequency on electrical parameters a) at higher frequencies, capacitance and impedance decrease while tan increases. b) at lower frequencies, heat generated by ripple current will rise due to an increase in equivalent series resistance ( esr). 1.2 operating temperature and life expectancy (1) expected life is affected by operating temperature. generally, each 10 reduction in temperature will double the expected life. use capacitors at the lowest possible temperature below the upper category temperature. (2) if operating temperatures exceed the upper category limit, rapid deterioration of electrical parameter will occur and irrev ersible damage will result. check for the maximum capacitor operating temperatures including ambient temperature, internal capacitor temperature rise due to ripple current, and the effects of radiated heat from power transistors, ic's or resistors. avoid placing components, whic h could conduct heat to the capacitor fr om the back side of the circuit board. (3) the formula for calculating expected life at lower operating temperatures is as follows ; ` = l 1 : guaranteed life (h) at temperature, t 1 l 2 : expected life (h) at temperature, t 2 t 1 : upper category temperature ( ) t 2 : actual operating temperature, ambient temperat ure + temperature rise due to ripple current heating( ) (4) please use according to the lifetime as noted in this specification. using products beyond end of the lifetime may change characteristics rapidly, short-circuit, operate pressure relief vent, or leak electrolyte. panasonic corporation * this specification guarantees the quality and perfor mance of the product as individual components. before use, check and evaluate their compatibility with installed in your products. * do not use the products beyond the spec ifications described in this document. * install the following systems for a failsafe design to ensure sa fety if these products are to be used in equipment where a de fect in these products may cause the loss of human life or other signification damage, such as damage to vehicles (automobile, train, vessel ), traffic lights, medical equipment, aerospace equipment, electric heati ng appliances, combustion/ gas equipment, rotating equipment, an d disaster/crime prevention equipment. ? the system is equipped with a protec tion circuit and protection device. ? the system is equipped with a redundant circuit or other system to prevent an unsafe status in the event of a single fault. * before using the products, carefully check the effects on their quality and performance, and determined whether or not they c an be used. these products are designed and manufactured for genera l-purpose and standard use in general electronic equipment. these products are not intended for us e in the following special conditions. 1. in liquid, such as water, oil, chemicals, or organic solvent 2. in direct sunlight, outdoors, or in dust 3. in vapor, such as dew condensation wate r of resistive element, or water leakage, sa lty air, or air with a high concentration corrosive gas, such as cl2, h2s, nh3, so2, or no2 4. in an environment where strong static el ectricity or electromagnetic waves exist 5. mounting or placing heat-generating components or inflamm ables, such as vinyl-coated wires, near these products 6. sealing or coating of these products or a printed circuit board on which these pr oducts are mounted, with resin and other ma terial 7. using resolvent, water or water-soluble cl eaner for flux cleaning agent after soldering.

engineering draft guideline-alv-s1-4 application guidelines guidelines-2 1.3 common application conditions to avoid the following misapplication load conditi ons will cause rapid deterioration of a capacitor?s electrical parameters. in addition, rapid heating and gas generation within the capacito r can occur, causing the pressure relief vent to operate and resultant leakage of electrolyte. under extreme conditions , explosion and fire i gnition could result. the leaked electrolyte is com bustible and electrically conductive. (1) reverse voltage dc capacitors have polarity. verify correct polarity before insertion. for circuits with changing or uncertain polarit y, use dc bipolar capacitors. dc bipolar capacitors ar e not suitable for use in ac circuits. (2) charge / discharge applications standard capacitors are not suitable for use in repeat ing charge/discharge applications. for charge/ discharge applicat ions, consult us with your actual application condition. (3) on-off circuit do not use capacitors in circuit where on-off switching is repeated more than 10000 times/per day. in case of applying to the theses on-off circuit, consult with us about circuit condition and so on. (4) over voltage do not apply voltages exceeding the maximum specified rated voltage. voltages up to the surge voltage rating are accept able for short periods of time. ensure that the sum of the dc voltage and the superimposed ac ripple voltage does not exceed the rated voltage. (5) ripple current do not apply ripple currents exceeding the maximum spec ified value. for high ripple cu rrent applications, use a capacit or designed for high ripple currents. in addition, consult us if the applied ripple current is to be higher than the maximum specified value. ensure that rated ripple currents that superim posed on low dc bias voltages do not cause reverse voltage conditions. 1.4 using two or more capacitors in series or parallel (1) capacitors connected in parallel the circuit resistance can closely approximate the seri es resistance of the capacitor, causing an imbalance of ripple cu rrent loads within the capacitors. careful wiring methods can minimize the possible application of an excessive ripple current to a capaci tor. (2) capacitors connected in series differences in normal dc leakage curr ent among capacitors can cause voltage imbalances. the use of voltage divider shunt resistors with c onsideration to leakage currents c an prevent capacitor voltage imbalanc es. 1.5 capacitor mounting considerations (1) double-sided circuit boards avoid wiring pattern runs, which pass between the mounted capacitor and the circuit board. (2) land/ pad pattern [table of board land size vs. capacitor size] [mm] abc a( 3) 0.6 2.2 1.5 b( 4) 1.0 2.5 1.6 c( 5) 1.5 2.8 1.6 d( 6.3) 1.8 3.2 1.6 d8 ( 6.37.7l) 1.8 3.2 1.6 e( 86.2l) 2.2 4.0 1.6 f( 810.2l) 3.1 4.0 2.0 g( 1010.2l) 4.6 4.1 2.0 h( 12.5) 4.0 5.7 2.0 j ( 16) 6.0 6.5 2.5 k ( 18) 6.0 7.5 2.5 size / dimension the land pattern and size shall be decided in consi deration of mountability, solderbility and strength. (3) clearance for case mounted pressure relief ( R 10 mm) capacitors with case mounted pressure relief require sufficient clearance to allow for proper pressure relief operation. the minimum clearance are dependent on capacitor diameters as follows. (dia 10mm dia 16mm : 2mm minimum , dia 18mm : 3mm minimum) (4) wiring near the pressure relief ( R 10 mm) avoid locating high voltage or high current wiring or circuit boar d paths above the pressure relief . flammable, high temperatu re gas that exceeds 100 ? c may be released which could dissolv e the wire insulation and ignite. (5) circuit board patterns under the capacitor avoid circuit board runs under the capacitor, as an el ectrical short can occur due to an electrolyte leakage. 1.6 electrical isolation of the capacitor completely isolate the capacitor as follows. ? between the cathode and the case and between the anode terminal and other circuit paths. 1.7 capacitor sleeve the laminate coating is intended for marking and identification purposes and is not meant to electrically insulate the capa citor. panasonic corporation land space
engineering draft guideline-alv-s1-4 application guidelines guidelines-3 2. capacitor handling techniques 2.1 considerations before using (1) capacitors have a finite life. do not reuse or recycle capacitors from used equipment. (2) transient recovery voltage may be generated in the capacitor due to dielectric absorption. required, this voltage can be discharged with a resistor with a value of about 1k . (3) capacitors stored for a long period of time may exhibit an increase in leakage current. this can be corrected by gradually applying rated voltage in series with a resistor of approximately 1k . (4) if capacitors are dropped, they can be damaged mechanica lly or electrically. avoid using dropped capacitors. (5) dented or crushed capacitors should not be used. the seal integrity can be damag ed and loss of electrolyte/shortened life can result. 2.2 capacitor insertion (1) verify the correct capacitance and rated voltage of the capacitor. (2) verify the correct polarity of the capacitor before insertion. (3) verify the correct hole spacing and land pattern si ze before insertion to avoid stress on the terminals. (4) for chip type capacitors, excessive mounting pressure can cause high leakage current, short circuit, or disconnection. 2.3 manual soldering (1) observe temperature and time soldering s pecifications or do not exceed temperature of 350 for 3 seconds or less. (2) if a soldered capacitor must be removed and rein serted, avoid excessive stress on the capacitor leads. (3) avoid physical contacts between the tip of the solder ing iron and capacitors to prevent or capacitor failure. 2.4 reflow soldering (1) surface-mount type capacitor are exclusively for reflow soldering. when reflow solder is used an ambient heat condition system such as the simultaneous use of infrared and hot-air is recommended . (2) observe proper soldering conditi ons (temperature, time, etc.). do not exceed the specified limits. the temperature on capacitor top shall be measured by us ing thermal couple that is fixed firmly by epoxy glue. (3) reflow should be performed one time. cons ult us for additional re flow restrictions. (4) in our recommended reflow condition , the case discol oration and the case swelling might be slightly generated. but please acknowledge that these two phenomena do not influence the reliability of the product. (5) the crack on top marking might be occurred by reflow heat stress. but please acknowledge that it does not influence the reliability of the product. (6) vps (vapor phase soldering) reflow can cause significant characteristics change and/ or m ounting failure due to deformation by acute temperature rise. vps is acceptable provided that the process does not exceed reco mmended reflow profile and temperature rise is less than 3degc/ sec. please contact panasonic for detailed conditions. 2.5 capacitor handling after soldering (1) avoid moving the capacitor after soldering to prevent excessive stress on the lead wires where they enter the seal. (2) do not use the capacitor as a handle when moving the circuit board assembly. (3) avoid striking the capacitor after assembly to prevent failure due to excessive shock. 2.6 circuit board cleaning (1) circuit boards can be i mmersed or ultrasonically cleaned using suit able cleaning solvents for up to 5 minutes and up to 60 maximum temperatures. the boards should be thoroughly rinsed and dried. the use of ozone depleting cleaning agents is not re commended for the purpose of protecting our environment. (2) avoid using the following solvent groups unle ss specifically allowed in the specification ; ? halogenated cleaning solvents : except for solvent resistant capacitor types, halogenated solvents can permeate the seal and cause internal capacitor corrosion and failure. for solvent resistant capacitors, carefully follow the temperature and time requirements ba sed on the specification. 1-1-1 trichloroethan e should never be used on any alum inum electrolytic capacitor. ? alkaline solvents : could reac t and dissolve the aluminum case. ? petroleum based solvents : deteriorati on of the rubber seal could result. ? xylene : deterioration of t he rubber seal could result. ? acetone : removal of the ink marki ngs on the vinyl sleeve could result. (3) a thorough drying after cleaning is required to remove residual cleaning solvents that may be trapped between the capacit or and the circuit board. avoid drying temperatures, which exceed the upper category temperature of the capacitor. (4) monitor the contamination levels of the cleaning solvents during use in terms of electrical conductivi ty, ph, specific gr avity, or water content. chlorine levels can rise with contamination and ad versely affect the performance of the capacitor. (5) depending on the cleaning method, the marki ng on a capacitor may be erased or blurred. please consult us if you are not certai n about acceptable cleaning solvents or cleaning methods. 2.7 mounting adhesives and coating agents when using mounting adhesives or coating agents to control humidity, avoid us ing materials containing halogenated solvents. also, avoid the use of chloroprene based polymers. harden on dry adhesive or coating agents well lest the solvent should be left. after applying adhesives or coatings, dry thoroughly to prevent residual solvents from being trapped between the capacitor a nd the circuit board. panasonic corporation
engineering draft guideline-alv-s1-4 application guidelines guidelines-4 2.8 fumigation in exporting electronic appliances with aluminum electrolytic capacitors, in some cases fumigation treatment using such halo gen compound as methyl bromide is conducted for wooden boxes. if such boxes are not dried well, the halogen left in the box is dispersed while transported and enters in the capacitors insid e. this possibly causes electrical corrosion of the capacitors. therefore, after performing fumigation and drying make sure that n o halogen is left. don?t perform fumigation treatment to the whole electronic appliances packed in a box. 3. precautions for using capacitors 3.1 environmental conditions capacitors should not be stored or used in the following environments. (1) exposure to temperatures above the upper category or below the lower category temperature of the capacitor. (2) direct contact with water, salt water, or oil. (3) high humidity conditions where water could condense on the capacitor. (4) exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, chlorine compound, bromine, bromi ne compound or ammonia. (5) exposure to ozone, radiation, or ultraviolet rays. (6) vibration and shock conditions exceeding specified requirements. 3.2 electrical precautions (1) avoid touching the terminals of a capaci tor as a possible electric shock could resu lt. the exposed aluminum case is not in sulated and could also cause electr ic shock if touched. (2) avoid short circuiting the area between the capacitor terminals with conductive ma terials including liquids such as acids o r alkaline solutions. (3) a low-molecular-weight-shiroxane which is included in a sili con material shall causes abnorma l electrical characteristics. 4. emergency procedures (1) if the pressure relief of the capacitor operates, immediatel y turn off the equipment and disconnect from the power source. this will minimize an additional damage caused by the vaporizing electrolyte. (2) avoid contact with the escapi ng electrolyte gas, which can exceed 100 temperatures. if electrolyte or gas enters the eye, immedi ately flush the eye with large amounts of water. if electrolyte or gas is i ngested by mouth, gargle with water. if electrolyte contacts the skin, wash with soap and water. 5. long term storage leakage current of a capacitor increases with long storage times. the aluminum oxide film deterio rates as a function of temper ature and time. if used without reconditioning, an abnormally high curr ent will be required to restore the oxide film. this surge current could cause the ci rcuit or the capacitor to fail. storage period is one year. when storage period is over 12 months, a capaci tor should be reconditioned by applying the rated voltage in series with a 1000 current limiting resistor for a time period of 30 minutes. for storage condition, keep room temperature (5 35 ) and humidity (45% 85%) where direct sunshine doesn't reach. 5.1 environmental conditions (1) exposure to temperatures above the upper category or below the lower category temperature of the capacitor. (2) direct contact with water, salt water, or oil. (3) high humidity conditions where water could condense on the capacitor. (4) exposure to toxic gases such as hydrogen sulfide, sulfuric acid, nitric acid, chlorine, chlorine compound, bromine, bromi ne compound or ammonia. (5) exposure to ozone, radiation, or ultraviolet rays. (6) vibration and shock conditions exceeding specified requirements. 6. capacitor disposal when disposing capacitors, use one of the following methods. (1) incinerate after crushing the capacitor or puncturing the can wall (to prevent explosion due to internal pressure rise). (2) dispose as solid waste. note : local laws may have specific dis posal requirements which must be followed. panasonic corporation
